[Variability in the longevity of Drosophila imagoes under chronic irradiation at low doses]

The investigation of life span variability induced by a chronic influence of low doses gamma irradiation on the laboratory stocks of D. melanogaster, distinguishing by mobile genetic units, were carried out. Shown was the link of life span alterations in D. melanogaster with features of cytotype and genotype in tested stocks and with induced apoptotic cell death. The life span variation can be determined by a genomic destabilisation with an induction of mobile genetic elements in conditions of chronic gamma irradiation.
